Evaluating Barriers to Stroke Screening & Prevention in Children With

Status Completed

Clinical Trial Summary

DISPLACE is a three part, multi-center U.S. based study to evaluate the barriers to stroke screening and prevention in children with sickle cell anemia (SCA). In the United States, TCD (Transcranial Doppler ultrasound) is a proven method of screening children with SCA for stroke. However, many children are not getting the screening they need. This study will examine the issues that hinder and help children get the screening at 28 different hospitals and sickle cell centers to improve care for all children with sickle cell anemia. The investigators will then plan a study (part 3) aimed to improve stroke screening and prevention in sickle cell anemia.

Clinical Trial Description

DISPLACE (Dissemination and Implementation of Stroke Prevention: Looking At the Care Environment) is a multi-center, national NHLBI-funded grant to evaluate the real world implementation of the STOP protocol in which transcranial Doppler (TCD), a measure of cerebral blood vessel velocity, is used to screen for stroke risk in children ages 2-16 with sickle cell anemia (SCA). Based on the STOP (Stroke Prevention Trial in Sickle Cell Anemia) protocol, children identified as high risk of stroke by TCD are initiated on chronic red cell transfusion therapy (CRCT) for stroke prevention. Children with normal TCD are screened annually from the age of 2 until they are 16 years of age.

This will be a THREE-part study beginning with Part 1 - a retrospective case record review followed by Part 2 - a multi-level qualitative assessment of barriers and enablers to TCD screening and initiation of chronic red blood cell transfusions and later adding Part 3 - a multi-center implementation clinical trial.The investigators will compare two implementation interventions to improve TCD screening.

There are three aims of the grant and each aim is equivalent to the respective parts of the grant (i.e. Part 1 covers 1 aim). There are a total 28 consortium sites. The Medical University of South Carolina is the lead institution for this study. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
